To all whom 'it 'mayconcern:

Be it known thatI-,VINCENT C. Dr. YBAR- nonno, a citizen of the UnitedStates, residing at Los- Angeles, in the county of Los Angeles and State of California, have in- 'vented new andiiseful Improvements in Removable Nails, .of which the following a specification.

- its. opening however being of a prescribed lrequires.

The invention consists of the features of construction, combination and arrangement of parts hereinafter fully described and claimed, reference heilig had to the accompanying drawin in wl'ch the single View given is a side e evation showing the use of the spacing Washers hereinafter' referred to..

Referring now more particularly to the drawing, the numeral 1 designates the shank of the nail andQ its head, which parts may be of any preferred form. Formed integrallywith the shank andhead at their point of junction is a collar 3, of greater diameter than the shank andof less diameter than the head so as to leave a flat shoulder 5' facing .downward awayV from the head.-

Designed for use in connection with the nail 1s a. Washer 4, which may be'of ordinary construction but preferably has flat faces,

diameter to snugly fit the shank 1, s'o that the washer will retain its position 'by friction on the shank, but may be forcibly adjusted or detached by a sliding movement.

In the practical use of the nail, the washer is applied in position and the naildriven into the partto be secured by blowsupon the head 2 from alli'amnier or other tool. The washer bearsjigaiust the outer vSurface of one of the parts, and, when the nail is fully driven in, the shoulder 5 at the lower end 91:' the collar 3 abuts a ainst said washer, thus preventing the nail rom being farther `driven. The collar 3 will thereby serve the function of a stop and spacing medium, so

that the head of the nail will be exposed in order to admit'o its being 'by" ,the claws of a hammertoefeet an easy-fand .convenient withdrawal thereof. Hence,the'

Patented NovfSrlQl-i parts may be securely united without dani--- f age thereto and may be readily disconnected at any time.

As shown in the drawing, the extent which the nail is driven into the wood may be varied by the 3, which additional washers will preferably conform in diameter to the use vof additional smaller spacing washers G between theiiat'faced 'washer 4 and the shoulder 5 'of the collar collar, `wherebyv the head of the nail, when the latter `iis Afully i driven in, will project to beyond the surfacefto allowthe head to be a greater extent more conveniently gripped when applied:

close to crannies or interfering o b'ects.

As an additional advantage resti tingfro'm the use of a removable Washer and the fixed collar, it may be stated tl1at.wasliers of difj ferent sizes may be employed to' suit diil'erf" ent conditions of service and to obviate liability of Splltting or otherwise injuring fragile woods.

An essentialcharacteristic of my inven` tion, however, consists in the,` fact that the diameter'of'the collar 3 (and the spacing Washers 6 ifiised) is less than the width of` the claw of an ordinary hammer, and the length' of said collar is greater than the thickness of said claw; hence the latter l.can be easily applied astride the collar and the nail removed without injury to lthe surface into which it has been driven. i

Having thiis fully described the invent-ion. what is claimed-as new is A removable ynail coniprisigja lieadf'a 'l shank, and acollarat their Junctlire integ'ral with bothv` smaller Ithan' 'the liead, d?

larger than the shank, and having-'a1` vfiat shoulder around the latter, a flatilfac'ed washeirof the diameter of said head-'andre in ovably but frictionally engaging tlieshunk. j

and a series of spacing washers of tli-ejdiameter'r'ofsaid collarand located "on the Ashank between 'the shoulder of-thefcollar and said flat-faced washer. I

In testimony whereof I ailixmy' signature in presence of two witnesses.\ g `VINCENT C. DE YBARROHDO. Witnesses: i
